Definitions

  • the present invention is generally related to interconnection cables for signal transmission and more particularly to an interconnection cable transmitting low frequency signals, preferably audio frequency signals; having insulated conductors, a woven shielding conductor of meshed wires surrounding said insulated conductors and an outer shell.
  • the proposed interconnection cable may be advantageously utilised in any connection between signal sources and amplifier units in high-fidelity audio systems.
  • the aim set is to ensure an audio system of total linear signal transmission and absolutely neutral operation.
  • an object of the present invention to provide an improved interconnection cable for transmission of low frequency signals, preferably of audio frequency signals, having a full linear signal transmission and absolutely neutral operation. It is also the object of the present invention to provide an improved interconnection cable for transmission of low frequency signals which achieves use of known and reliable technologies.
  • the invention is due to the recognition that a full linear signal transmission could be achieved with a relative thick conductor made of few components instead of further increase of the number of the wires forming the conductor.
  • An interconnection cable for transmission of low frequency signals comprises insulated conductors laid together, a shielding conductor of woven wires covering said insulated conductors and an outer shell.
  • a core ensuring mechanical strength of the cable is surrounded by at least four insulated conductors forming first and second, signal path of the cable in equal number; the conductors are surrounded by a insulation layer of foamed non-polar plastic and the shielding conductor is made of a fabric layer with a density of 55 to 95 % woven of copper wire having a diameter in order of magnitude of several tenth millimetres.
  • the core of the cable is formed of a solid, untinned, oxygen-free copper wire with a diameter of 0.8 mm. This feature is advantageous because the copper wire forming the core ensures increased mechanical strength for the cable; this wire can be utilised for the transmission of a further signal, e.g. a remote control signal being independent from the transmitted main audio signal.
  • the core is surrounded by six insulated conductors, three of them forming the first signal path and three of them forming the second signal path of the cable and having an outer diameter causing a continuous ring around the core abutting each other. Due to this feature a cable with proper electrical (linearity) and mechanical (thickness) parameters can be produced.
  • the insulation layer is formed of foamed polyethylene with an average space factor of 40 to 60 % and the shielding conductor is formed as a fabric layer with a density of 75 % woven of copper wire having a diameter of 0.2 mm. According to a overwhelming majority of hearers of the tests the best results can be achieved with a cable having the afore-mentioned features.
  • the conductors forming the first and second signal path of the cable have insulation layers of different colour to facilitate the montage of the cable.
  • the conductors are lined parallel with the core in the cable. This construction yields in optimal acoustical properties according to the measurements on the cable.
  • the described interconnection cable according to the invention is suitable for connection of two monaural audio equipment.
  • two cables of same type should be utilised.
  • the final interconnection cable is quite rigid but can be deformed without any damage. No trouble due the rigidity of the cable has been observed in the plurality of the applications.
  • the Figure is a cross sectional view of an interconnection cable embodying the present invention.
  • FIG. 1 there is illustrated a cross sectional view of an interconnection cable ac ⁇ cording to the invention.
  • the cable has a core 1 made of solid, untinned, oxygen-free copper wire with a diameter of 0.8 mm.
  • the core 1 is surrounded by six insulated outer conductors 2 having an outer diameter causing a continuous ring around the core 1 abutting each other.
  • the copper wire forming the core 1 and the conductors 2 are separated from each other by a foamed polyethylene insulation layers 3.
  • Two groups of each three conductors 2 forming first and second signal path of the cable and the core 1 have an insulation layer 3 of different colour for an easy identification.
  • the material of the insulation layers 3 is a first foamed microcell polyethylene layer with an average space factor of 60 % and a thickness of 0.4 to 0.6 mm, and a second polyethylene skin layer with a thickness of 0.03 mm, applied in a single production step.
  • the arrange ⁇ ment and the distance of the core 1 and the conductors 2 from each other is determined by the production and this ensures the optimal geometrical and acoustical parameters without any measurement during or after the production.
  • the semi-fabricated cable is provided with a shielding conductor 4 made of a fabric layer with a density of 75 %, woven of copper wire having a diameter of 0.2 mm.
  • the shielding conductor 4 is covered with an outer shell 5 made of solid polyethylene layer with a thickness of 1 mm.
  • the full diameter of the cable described above is cca 7.5 to 8.5 mm.
  • the insulation layer 3 of the cable can be made of polytetrafluoroethylene with a minimal technological amendment. This results in better electrical (acoustical) parameters and an increased rigidity which should taken into consideration during installation and use of the cable.

Abstract

Câble d'interconnexion pour la transmission de signaux à basse fréquence, de préférence des signaux audio. Il comprend une âme (1) assurant la résistance mécanique du câble et entourée d'au moins quatre conducteurs isolés (2) formant un premier et un second trajet de signaux, dont chacun est constitué de deux conducteurs respectifs. Les conducteurs (2) sont revêtus d'une couche isolante (3) en matière plastique cellulaire et apolaire. Un conducteur de blindage (4) est constitué d'une couche de tissu, dont la densité est comprise entre 55 et 95 %, tissée à partir de fils de cuivre présentant un diamètre de l'ordre de quelques dixièmes de millimètre. Une chemise extérieure (5) en matière plastique solide recouvre l'ensemble constitué de l'âme (1), des conducteurs (2) et du conducteur de blindage (4).
